OK, Time for a Gummy rant:
I believe that the atomization process is way out of balance on mine with this tea bag wick. (no big surprise after all I am not using the recommended parts), but I wanted to play. So I will stop playing around with it until I get the proper mesh. I think that the droplet size is not small enough. Not to get to far into the physics but, the atomization balance is different for spray painting than it is for smoking. These droplets are just to big and wet. it is more like a mist than smoke, that's why there is no big cloud of exhale smoke. the big wet droplets are sticking inside the lungs. it's not dry enough. (not by much, it is close, it could only be the difference between .3 micron or .8 microns). so I am hoping that the SS wick will provide more mass to flash the droplets smaller, thus dryer.
Dr. Raidy has said that changing the mesh count changes the end product between strong throat hits or lots of vapor. What this is doing is changing the droplet size of the smoke. Altering the surface tension of the liquid controls the droplet size. This is constantly being altered in several ways. 1, viscosity of fluid. 2, energy. 3, quantity, (fluid flow rate, ie: wicking). Pressure doesn't really come into play with PVs.
We moders play with energy all the time with variable voltage units or different resistance of the atty.s. We use energy to adjust for the different viscosity of fluid (or subtle flavor additives, PG/VG and such) . Quantity is easily seen when an atty is flooded or dry, (either extreme will not taste good). But it plays a part in the volume of smoke produced. We see this a lot on the video reviews by watching someone blow out a ton of vapor when they exhale. (smaller droplet size= dryer vapor that doesn't stick to anything that it comes in contact with like my lungs or the air). It all goes back to how to alter the surface tension to find a balance that each of us would like. There is a happy balance that we all look for that's different for each of us and for different e-juices/flavor additives. ,,, and when we find it, damn it's soon gone, because one of those values just went out of balance.
